Arid3a modulates the first cell fate decision by direct regulation of both embryonic and extraembryonic gene expression (microarray)

ABSTRACT: Arid3a, a transcription factor known for its requirement in B-lymphocyte development, has been recently identified as a member of ES cell pluripotency network. Arid3a is moderately expressed in ES cells, and its expression is gradually increased during differentiation. Since Arid3a shows the highest expression in placenta, we hypothesized that Arid3a may play important roles in TE development. We report that Arid3a is a central regulator of both TE-specific and pluripotency-associated gene expression during ES cell differentiation. While dispensable for self-renewal, we observed that knockdown of Arid3a delays differentiation of ES cells. Induction of Arid3a leads ES cells to promote differentiation, specifically towards TE lineage. Moreover, these Arid3a-overexpressing cells maintained in TE culture media are sufficient to generate functional trophoblast stem-like cells, suggesting roles of Arid3a in TE differentiation. By integrative analyses using the chromosomal targets of Arid3a with expression profiling, we revealed the dual roles of Arid3a, as a direct activator of TE-specific genes and a repressor of pluripotency-associated genes. We further revealed the repressive roles of Arid3a are mediated by histone deacetylases (HDACs). Taken together, our results demonstrate that Arid3a is a critical novel regulator in TE lineage specification.

Arid3a is required for mammalian placenta development

Project description:Previous studies in the mouse indicated that Arid3a plays a critical role in the first cell fate decision required for generation of trophectoderm (TE). Here, we demonstrate that Arid3a is widely expressed during mouse and human placentation and essential for early embryonic viability. Arid3a is located within trophoblast giant cells and other trophoblast-derived cell subtypes in the junctional and labyrinth zones of the placenta. Conventional Arid3a knockout embryos suffer restricted intrauterine growth with sever defects in placental structural organization. Arid3a null placentas show aberrant expression of subtype-specific markers as well as significant alteration in inflammatory response-related genes, cytokines and chemokines. We provide evidence that BMP4-mediated induction of trophoblast stem (TS)-like cells from human induced pluripotent (iPS) stem cells results in ARID3A upregulation and cytoplasmic to nuclear translocation. Overexpression of ARID3A in human iPS and BMP4-mediated TS-like cells up-regulated TE markers, whereas pluripotent markers were down-regulated. Our results indicate that the roles of Arid3a are conserved and essential for mammalian placental development through regulation of both intrinsic and extrinsic developmental programs. Placentas of E10.5 and E11.5 wild type (WT) and Arid3a-/- mice were generated by deep sequencing, using Illumina

ARID3A coordinates the proliferation-differentiation switch of transit-amplifying cells in the intestine

Project description:Intestinal stem cells (ISCs) at the crypt base divide and give rise to progenitor cells that have the capacity to proliferate and differentiate into various mature epithelial cell types in the transit-amplifying (TA) zone. Here, we identified the transcription factor ARID3A as a novel regulator of intestinal epithelial cell proliferation and differentiation at the TA compartment. We show that ARID3A forms an expression gradient from villus tip to the early progenitors at the crypts mediated by TGF-β and WNT signalling. Intestinal epithelial-specific deletion of Arid3a reduces proliferation of TA cells. Bulk and single cell transcriptomic analysis shows increased enterocyte differentiation and reduced secretory cells in the Arid3a cKO intestine. Interestingly, upper-villus gene signatures of both enterocytes and secretory cells are enriched in the mutant intestine. We find that the enhanced enterocyte differentiation in the Arid3a cKO intestine is caused by increased binding of HNF1 and HNF4. Finally, we show that loss of Arid3a impairs irradiation-induced regenerative process by altering the dynamics of proliferation and apoptosis. Our findings imply that ARID3A may play a gatekeeping role in the TA compartment to maintain the “just-right” proliferation-to-differentiation ratio for tissue homeostasis and plasticity

Titration of Sall4 by the NuRD complex facilitates neural differentiation of ES cells

Project description:Sall4 is a transcription factor essential for early mammalian development. Though it is reported to play an important role in embryonic stem (ES) cell self-renewal, whether it is an essential pluripotency factor has been disputed. Though Sall4 is known to associate with the Nucleosome Remodeling and Deacetylase (NuRD) complex, the nature of this interaction is unclear as NuRD and Sall4 serve opposing functions in ES cells. Here we use defined culture conditions and single-cell gene expression analyses to show that Sall4 prevents activation of the neural gene expression programme in ES cells but is dispensable for maintaining the pluripotency gene regulatory network. We further show using genome-wide analyses that while Sall4 interacts with NuRD, it neither recruits NuRD to chromatin nor influences transcription via NuRD. Rather we propose a model where, by titrating Sall4 protein, NuRD limits the differentiation-inhibiting activity of Sall4 in ES cells to enable lineage commitment.
